The cabinet H is divided into a machinthermore, since the draft liquid cooler is removery compartment l2 and a refrigerated compartable and replaceable as a unit, it is an easy matment I3 by a heat insulated partition Ill. A ter to replace or repair the draft liquid cooler. motor-compressor unit M, a condensing element From the foregoing, it will be apparent that I I5, and'a distributing valve I6 are disposed in have provided a bottled beverage cabinet which 55 may be provided with a novel draft liquid cooler at minimum expense, and which draft liquid cooler is removable and replaceable by merely making or breaking liquid supply connection. In addition, the draft liquid is readily accessible exteriorly of the cabinet. No refrigerant or gas connections need be broken in removing or replacing the draft liquid cooler, and, therefore, the dangers of escaping refrigerant or loss of charge from the refrigerating machine are avoided.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of the beverage therein, said means being mounted in said beverage compartment independently of said closure, a member supporting said draft liquid cooling vessel in said cabinet and forming a portion of said closure means, and a connection for conveying cooled liquid from said draft liquid cooling vessel to an accessible portion at the exterior of said cabinet, said cooling vessel, supporting member and connection being removable from said cabinet sa a unit.

2. In a liquid cooler, the combination of an insulated cabinet embodying a compartment to be refrigerated, means for extracting heat from said compartment, a container for the liquid to be cooled disposed in said compartment, means for conveying liquid from said container to an accessible portion of the exterior of the cabinet, a liquid supply conduit for said container, means for detachably connecting the liquid supply conduit to said container, a drain for the liquid disposed adjacent the aforesaid accessible portion of the cabinet, and a liquid drain conduit extending exteriorly of said cabinet, said drain conduit being spaced from the drain for the liquid in a position to receive liquid from said drain, so that said container is removable as a unit from said cabinet upon disconnection of said supply conduit only.

3. In refrigeration apparatus, the combination of an insulated cabinet containing a chamber for a refrigerated liquid bath, means for abstracting heat from said bath, a removable cover for said cabinet, a cooling vessel for draft liquids immersed, at least, in part of said refrigerated bath, and draft liquid inlet and outlet connections for said cooling vessel extending through and attached to said cover, said cover and draft liquid cooling vessel being removable from said cabinet as a unitary structure by disconnecting the draft liq'uid inlet connection from said cooling vessel and without affecting the heat abstracting means.

4. In liquid cooler, the combination of an insulated cabinet containing a chamber for a refrigerated liquid bath, a removable cover provided on the cabinet, a cooling coil disposed in 'said chamber and supported independently of unitary structure.

said cover for abstracting heat from said chamber, a cooling vessel for draft liquid inserted, at least, in part of said chamber, and inlet and outlet connections for said cooling vessel extending through and attached to said cover, said cover and draft liquid cooling vessel being removable from said cabinet as a unitary structure when the inletconnection to said draft liquid cooling vessel is disconnected, and without affecting said cooling coil.

5. In a liquid cooler, the combination of an insulated cabinet having a removable cover, a container for a liquid bath in said cabinet, a refrigerating system having connected thereto a cooling coil for abstracting heat from said container, said cooling coil being disposed in said liquid bath independently of said cover, a draft liquid-cooling vessel attached to and depending from the cover and inserted, at least in part, in the refrigerated container, a draft liquid inlet connection for said cooler extending through and attached to said cover, and a faucet for controlling the withdrawal of the draft liquid mounted on said cover and connected to said inlet connection and saidcooler, said cover, faucet, and draft liquid cooler being readily removable from the cabinet as a-unit when said inlet connection is disconnected and without breaking the connections between the cooling coil and said refrigerating system.

6. In a liquid cooler, the combination of an insulated cabinet having a container for a liquid bath, a removable cover for said container, a draft liquid cooling vessel attached to and depending from the cover at least in part into said container, means mounted in the cabinet independently of said cover for abstracting heat from said container, and a faucet mounted on the cover and connected to said draft liquid cooling vessel for controlling the withdrawal of the draft liquid, said cover, draft liquid cooling vessel, and faucet being readily removable from the cabinet as a 7. In refrigeration apparatus, the combination of a cabinet embodying a water-tight storage compartment having an access opening in its top, closure means for said access opening, said storerage to be cooled, a draft liquid cooling vessel .inserted in said storage compartment, means for abstracting heat from said storage compartment disposed within said storage compartment independently of said closure, a member for supporting said draft liquid cooling vessel, at least in part, in said storage compartment and forming a ortion of said closure means, said draft liquid cooling vessel and supporting member being removable from said cabinet as a unit.

8. In refrigeration apparatus, the combination of an insulated cabinet containing a chamber for a refrigerated liquid bath, means for abstracting heat from said bath, a removable wall in said cabinet, a cooling vessel for draft liquids immersed, at least, in part of said refrigerated bath, and draft liquid inlet and outlet connections for said cooling vessel extending through and attached to said movable wall, said removable wall and draft liquid cooling vessel being removable from said cabinet as a unitary structure without affecting the heat abstracting means. by disconnecting the draft liquid inlet connection from said cooling vessel.
